You can watch my complete walkthrough video for the full game here, or use the step-by-step text/photo walkthrough below:

Chapter 1:

1. Look inside the box and solve the tile puzzle to get a camera:

2. Tap on the desk on the it side of the room and pick up the key.

3. Use the key to open the door to the left and enter the bathroom.

4. Take the screwdriver. Leave the bathroom and use the screwdriver to open the vent. Take the knife.

5. Use the knife to slash open the mattress and get another key.

6. Use the key on the door to the right and go through it.

7. Take the right path and then tap on the door to the right that says “Staff Only”. Scan your thumbprint and the door will open (are you hospital staff??).

8. Tap the desk lamp so it highlights a key. Take the key. Then turn the lamp to face the room.

9. Zoom out and you can see the rest of the room now. Turn on the computer and look through the files. You need a keyboard.

10. Exit the computer and open the file cabinet with the key you found. Look through the files.

11. Look at the poster on the wall.

12. Leave that room and enter the Nursery. Pick up the two cards from the table and read through the book.

13. Leave that room and enter the Waiting Room. Look at the picture of the radio and take a photo of it. Then pick up the iPad on the table and play the game (looks like Zelda?). Go into the house and pick up the key.

14. Leave the house and pick up the lantern. Follow the path to the trees and then find lantern oil. walk around and find a red person. Talk to him.

15. Then go back to the first screen and use the lantern to enter the cave. Follow the arrows until you find a chest and use the key to open it and get a puzzle piece.

16. Go back to the middle of the hallway and take the left path towards the library. Enter Patient Room 2. Pick up the banana from under the couch and look at the symbol on the other one (same as from the iPad game).

17. Pick up the mirror. Pick up the token from the table. Look at the writing on the couch.

18. Leave that room and enter the Library. Look around, then leave.

19. Enter Patient Room 3. Pick up the painting. Pick up the keys and the etching pencil from the desk. Leave that room.

20. Enter the Storage Room. Pick up the wrench. Read the book then leave the room.

21. Go back to the other end of the hallway until you see a door that asks for a token. Put the token into the slot.

22. Choose the far-right door and enter. Take the puzzle piece from the table, then leave.

23. Go to the desk with the computer and use the etching pencil on the piece of notebook paper to get the username and password for the computer:

24. Enter the username and password into the computer an read through the files. Then unlock the electronic door and enter it.

25. Go back to Patient Room 2 and use the wrench to remove the loose tap.

26. Go back to Patient Room 3 and match the puzzle on the floor to the drawing you saw earlier:

27. You’ll get the dial for the radio. Attach it to the radio near the computer and match it to the photo of the radio:

28. The radio will start playing chimes. You need to repeat this tune on the xylophone in the Nursery. The sequence is (from left to right), first, third, first, last. Once you solve it, you’ll get a ball card, a key card and the square puzzle piece.

29. Go to the other end of the hall and swipe the key card in the key reader to open the door.

1. There’s a clock in here. There’s also a clock back where we came from near the radio. Set both clocks to the same time (I chose 7:00). Then press both keys at the same time to unlock the door:

2. Don’t enter the room yet. Tap in the corner to the left and there will be a table with a pair of glasses on. It. Take the glasses and open the book on the ground. Put the glasses on to see this:

3. Go back and take the stairs up. There are some hieroglyphs but you can’t solve this puzzle yet so go back down.

4. We have some clues for the keypads on the wall. Here’s A:

And here’s C. Still missing B.

5. Go back all the way to the first room and enter the bathroom. Place the tap on the sink and turn on the hot water to get hieroglyphs in the mirror:

6. Go back to Patient Room 3. Place the mirror on the wall where the painting was and rotate it until it makes these words:

7. Go to the Library and open the book “This Cold World” and turn to page 798 to see these symbols:

8. Go to the hieroglyphs wall and press the hieroglyphs we’ve seen so far:

9. Go back down to the Staff Office and look at the files again. Put on the glasses to view the folder and you’ll see another symbol:

10. Go to the desk with the radio and computer. Use the keys to open the locked cabinet and take the circuit board. Place the circuit board by the Solitary Confinement door and complete the circuit to open the door:

11. Enter and pick up the keyboard. One of the walls has a connect-the-dots. Take a photo of it and draw on it to connect the dots and get two more hieroglyphs:

12. Go back to the Staff Office and place the keyboard by the computer. The poster in that room tells you to “Glitch” (Google) “The Answer”. So type that into the search bar and you’ll get a couple of the books that need to be pressed in:

13. Press the new hieroglyphs we found:

14. Go back downstairs. Enter the room ahead with the buttons and switches. Hold down the buttons to see what B =. Flip the switches below the buttons until you get the answer:

17. Continue ok and through the door. Pick up the book. Take the stairs up and take he puzzle piece off the cardboard person:

18. Go back downstairs and go to the room on the right to see some constellations:

go to the computer at the reception desk. type in the username and password that was you find on the notepad on the reception desk (you need to use the pencel for that) in one of the files it will say that the patient keeps repeating a number…..thats you’re code

We still don’t know who the guy is. The letter something along the lines that “subject 47a (the guy) woke up confused but then went through the puzzles; but that the subject is leaving the maze so the experiment is moving to stage 2″

I’m not to sure what to think about tht ending myself….its pretty obvious in the game title “lost …..ep 1″, tht there will be more episodes. But I, myself coulda’ thought of a hundred different ways to end it, or continue it……blah!
But I loved it til the end…..

The A code is in the patient filing cabinet in the office staff rm. The B code is in the room where you turn both keys at once. Adjust the lights for the code to appear. The C code is the screen saver that shows up after watching “good things come to all who wait” on the computer where the filing cabinet is.

I am playing forever lost on my Kindle Fire. I have been unable to enter the username and passcode from the computer at the reception desk that opens the electronic door because there isnt a return or enter key on the Kindle Fire keyboard. I revealed the correct username and passcode from the scetch pad I pencil’d on. I have never had problems with typing on the keyboard before. I purchased and downloaded from Amazon a few days ago it was fairly new only had a couple of reviews and noticed another reviewer was having the same problem. Is this a developer error or glitch? Or is there a simple step I’m missing? I cant finish the game without being able to open the electronic door can I? What to do?

I’ll ask again-I can’t get the electric door open using the username and password on that computer next to the etched paper. I have the username and password correct, but when it asks “hello Alice what would you like to do today?”, I don’t know what to type, nothing works. Help!

Hi, I have the username and password ( AJWHITE,PA55WORD), but, what do I do now? I mean, I know I need to write on the screen computer, but it’s not working.
I have to write them together ( username and password) in the same space?
I’m freaking out!!!

I’m cant pass trought the cock part! I know I have to set both clocks with the same time and then click both levers together, but its not working. Appears that I’m not pushing then at the sane time! What should I do???

Finished the game, took the elevator, went through the corridors and ended up in the control room. Facing all these screens. Now I can’t do anything anymore! There’s no reaction on anything that I do. Help!

I Need Help! I Cant Solve The Zodiac Puzzle! I Have Found 3 Of The Symbols, but in Hint 50D I Says I Should Use The Glasses In The First Page In The “filling cabinet”. But I Dont Know What It Means! Please Help and Reply As Soon As Possible…

I can’t “turn both keys at the same time”. What am I suppose to do? I’m stuck at Chapter 2 Number 1. And since you said that you have to set both clocks at the same time, I did it but only to their minute hand. Considering that the hour hand wouldn’t move. Ex. 4:55 and 10:55. Help.

It just says that the first room you awoke in (the one with the dirty mirror) was an observation room. You were being watched the whole time. Now you are moving to the research office and its time to unleash the next step.

Hiya! I’m at the end of this game. I’ve got the letter in my hands from subject 47a. I cannot do anything. I can’t move or go back. I read there is a door on the left, but i’m stuck. What can i do/ or am i supposed to do? Pls tell! Thx

Sorry that you have hit that, it’s an easy fix though. All you have to do is fully quit out of the app via the multi-tasking bar and then reload it ( all progress will have been saved ). Then when you’re in just move back to the reception and load up the clock above the desk and spin the hands anywhere.

Not being able to put down the banana was indeed a huge bug of this game. The symbol on the banana appears on the iPad game. You go there and use your UV glasses to see one of the four icons you need to line up in a different puzzle.

I took screenshots of every clue I was provided EXCEPT for that one. Days later when I continued the game I didn’t remember what symbol it was.

I’d swear the first time I opened the filing cabinet that it showed a cassette tape that I could click to play. I wasn’t in a location convenient for playing the tape, so I thought I’d go back later. I could never find the tape after that first time. Any ideas?
